<P>PROBLEM TO BE SOLVED: To determine whether or not a target document is a document modified from a document to be compared. <P>SOLUTION: A similar document determination device executes: a step for preliminarily storing determination processing data about a document to be compared in a determination processing data storage unit 13; a step for generating determination processing data about a target document by inputting the target document into a preprocessing unit 11; a step for using a similarity determination processing unit 12 to retrieve each piece of the determination processing data about the document to be compared from the determination processing data storage unit 13 and to compare the retrieved data with the determination processing data about the target document; and a step for executing similarity determination processing based on determination processing criteria held by the similarity determination processing unit 12. Therefore, the similar document determination device can determine whether or not the target document is a document modified from the document to be compared. <P>COPYRIGHT: (C)2012,JPO&INPIT |
